Choristoneura fumiferana antifreeze protein (CfAFP)
This family consists of several antifreeze proteins from the insect Choristoneura fumiferana (Spruce budworm). Antifreeze proteins (AFPs) and antifreeze glycoproteins (AFGPs) are present in many organizms that must survive sub-zero temperatures. These proteins bind to seed ice crystals and inhibit their growth through an adsorption-inhibition mechanism.
